1. Apparatus, comprising:
at least one processor; and
at least one memory storing instructions that, when executed with the at least one processor, cause the apparatus to perform:
receiving an image from a camera sensor;
receiving selection of one or more target objects appearing in the image;
tracking the one or more target objects over a plurality of subsequently-received images;
for respective images of the plurality of subsequently-received images in turn:
determining one or more performance metric(s) associated with estimated performance of a fill-in processing operation of the one or more tracked target objects, wherein the one or more performance metric(s) are determined based, at least partially, on one or more parameters associated with at least one of:
a processing time, or
a power
associated with the estimated performance of the fill-in processing operation for the one or more tracked target objects; and
saving the image as an optimized reference image in the event that the respective one or more performance metric(s) indicate an improved performance over that of one or more previously-received images from a time of receiving the selection; and
performing the fill-in processing operation for a saved optimized reference image of one or more saved optimized reference images, using one or more pixel values of the saved optimized reference image, for output to a display screen.
